Opening with a phone

A phone-controlled door lock changes the way you use the entrance to your home, office or apartment. Instead of a key you use a smartphone and an app to open the door in seconds — or hand out access to other people. It's especially valued by owners of rental apartments, hotels and anyone who wants full control over who enters and when. Digital access, remote management and no more lost-key issues make it a convenient, modern alternative to traditional locks.

The TTLock app (and Tuya) is the control centre for a smartphone-operated lock. Available on Android and iOS, it lets you:

• Unlock or lock the door remotely from anywhere in the world
• Create virtual keys for family, staff or guests
• Generate one-off or time-limited PIN codes
• Track activity in real time — who used the lock and when
• Receive notifications on every entry

Communication with the lock uses Bluetooth (nearby) or Wi-Fi via the Wi-Fi G2 gateway (from anywhere). Data is protected with AES encryption, and access can be revoked instantly from the app if a device is lost.

Hotels & commercial buildings — the reception grants room access remotely before the guest arrives, codes deactivate automatically at check-out, and lost-key replacement costs disappear. The TTLock H15B model was designed with hospitality in mind.

Short-term rentals (Airbnb, Booking) — the owner generates a code valid only for the reservation dates; guests type the code or unlock the door with their smartphone. Around 40% of guest complaints in Airbnb concern key logistics — a phone-controlled lock removes that friction entirely.

Family homes & apartments — assign individual codes to household members, generate temporary codes for guests or a courier, review entry history in the app, and instantly revoke access if you lose your phone. Battery life is around a year on 4×AA cells, and the app warns you about low battery in advance.

If you're looking for a lock for a short-let apartment with TTLock support, or a solution for an office or family home, it's worth starting with a few simple steps:

1. Identify the door type — measure the leaf thickness, check the current lock and whether you have a certified insert to replace or keep
2. Define the main use case — short-term rental needs different features than a single-family home or a commercial venue
3. Estimate the number of users — how many people will use the lock, how many codes or digital keys you need
4. Determine integration requirements — do you want to connect the lock to a smart-home system, Google Home or Alexa
5. Consult an expert — a professional consultation avoids mistakes and pinpoints the optimal model
